2 (x - 1)^{2} = 72

x = 7, x = - 5

Solution steps

2 (x - 1)^{2} = 72

Divide both sides by

2

(x - 1)^{2} = 36

For

(g (x))^{2} = f (a)

the solutions are

g (x) = f (a), - f (a)

Solve

x - 1 = 36 : x = 7

Solve

x - 1 = - 36 : x = - 5

The solutions to the quadratic equation are:

x = 7, x = - 5

3 (x - 4)^{2} + 15 = - 9

9 x^{2} + 12 x = - 6

x, 3 x^{2} + x + 1 = 0

2 x^{2} + 9 x - 11 = 0

x^{2} = \frac{8}{3}
